' INVENTOR. PHILIP J. BREWINGTON Y ii kvih United States Patent 3,263,240 REPLACEMENT FLUSH VALVE Philip J. ltrewlngton, 6401 Emerald St., Austin, Tex. Filed June 30, 1964, Ser. No. 379,311 4 Claims. (Cl. 4-57) This invention relates to replacement flush valves and has for its principal object the provision of an assembly which can accurately and quickly be installed over an existing flush valve seat by an ordinary person with no previous experience.

Another object of the invention is to provide a replacement flush valve which is simple, inexpensive, durable and unlikely to get out of order.

A further object of the invention is to provide a device which can be installed in the majority of water closets with no adjustment to the old valve and in which the new seat is spring-pressed into contact with the old seat.

In the drawings:

FIGURE 1 is an elevation of the device as sold, certain of the portions being in section.

FIGURE 2 is a top plan view.

FIGURE 3 is a section on line 3-3 of FIGURE 1.

FIGURE 4 is a view similar to FIGURE 2, but showing the outlet and overflow pipes as well as the usual bracket clamped to the overflow pipe.

FIGURE 5 is an elevation, partly in section, showing the replacement assembly as installed.

Referring to FIGURE 5 first, showing the assembly as installed in a typical toilet flush tank, the old parts which which will be retained after disposing of the worn ball and its vertical stem are: the tank having a bottom 11 in which the outlet pipe 12 with its worn tapered seat 15 is held by the usual flange 16 and nut 17 and which is secured against leakage by the rubber gaskets 18; the overflow pipe 20 and the bracket 21 (FIGURE 4) clamped as at 22 at right angles to the bracket portion which has on its free end a guide 23 for the discard d-Stem of the worn ball. This bracket is retained as it furnishes a conven ient anchor for the spring which holds the new assembly in place. The means for raising the old ball'is also retained as the function is the same and may be of any of the usual forms including a chain or a wire, etc. This well-known means is illustrated as having a link 25 on shaft 26 with lever or handle 27 controlling the manual lifting of the new flush ball 30 by a connection 31 which may be a wire curled around the top of the tube 33 as at 34 and around the pin 35 at the end of link2$ as at 36.

The replacement assembly as furnished is shown in FIG- URES 1 to 4. This includes the cylindrical portion31 of the valve seat member flanged as at 38 and with its lower rim 39 well free of engagement with the old seat 15 so that the large gasket 40, preferably secured to the flange 38, resists the downward spring pressure described later. The cylindrical portion 37 has a valve seat 41 at enlargement 43 tapped to receive the threaded lower end 55 its top and has centrally a strut 42 (FIGURE 3) with an Patented August 2, 1966 44 of the stem 45 of a P-shaped element of spring metal anchored in the opening of the formerly used guide end 23 of the bracket 21. The P-shaped element is bent as at 46, 47, 48, 49 so that the stem 45, the mid-section 28 and the upstanding short anchor portion 50 are parallel so that the new valve seat member 37 is firmly held in place between the threaded strut 42 and the bracket 21, thus compressing the large rubber gasket 40. By pulling down the short anchoring portion 50 to free it from bracket 21, the entire assembly can easily be lifted out and as readily be installed by placing it over the old valve seat and then lowering the tube 33 in the ball 30 until the tube bottom 29 touches the small rubber washer 32 thus preventing leakage through the tube 33.

The flush ball or valve closure 10 includes a seat engaging member 52 preferably flat, but which may be slightly conical, and a central metal tube 33 having a flaring upper end 51 to form a stop for the connection 31 which, when not of wire, may be slipped on the tube before the latter is placed in the ball where it is frictionally held in adjusted position. Since the seat engaging member 52 rests upon new seat 41 quite well inward of the periphery of the ball at that level, the water pressure on the flexible lip of the ball will insure against leakage even if the stem 45 is not precisely vertical.

What is claimed is:

1. A toilet flush valve assembly to replace a worn ball closure and add a new valve seat, while retaining the old valve seat comprising a new ball closure, :1 member eoaxial with the old seat and the outlet closure pipe and having at its upper surface a replacement seat to receive the new ball closure and means adapted to resiliently urge the replacement seat toward the retained valve seat, said urging means comprising a spring adapted to be secured at one end to the coaxial member and detachably anchored at the other end in it retained guide bracket formerly used to guide the stern of the worn valve closure.

2. The assembly of claim 1 in which an upwardly directed portion of the spring loosely enters the guiding opening of the bracket.

3. The assembly of claim 1 in which the spring has a threaded connection with a portion of the coaxial member. 4. The assembly of claim 1 in which the spring is P-shaped, the coaxial member has a central strut, and the spring has a threaded connection with the strut.
